Re: [libvirt] [PATCH v2 2/5] uml: Fix umlInotifyEvent dom object handling

The virDomainObjListFindByName will return a locked and reffed object. If we call virDomainObjListRemove that will unlock the object upon return, thus we need to relock the object before making the call to virDomainObjEndAPI.
